In this report, the mechanical and thermal properties of a 2D-SiCf/SiC composite made by the CVI-process with the Hi-Nicalon (Trademark) type S fabric are assessed in detail with respect to meeting fusion design requirements. Minimum strength and stiffness structural requirements likely can be met by CVI-processed SiCf/SiC composites when made with advanced SiC fibers. Unfortunately, it appears unlikely that the minimum thermal conduction goals can be met for CVI-processed material. Even for an optimized 2D SiCf/SiC system, the margin of improvement required is just too large for only minor improvements potentially possible through CVI-processing upgrades or other structural or architectural methods.
